I suggest you ...

Show full file/folder name

I know lots of apps use the ellipsis/three dots (...) when the text reaches a character limit, but I think it's a little annoying when you have to go to the properties of the file/folder just to see it's full name. Just make a new type of view (detailed view?) or make it as an option in settings.

This is similar to a request I raised. I appreciate the ... sometimes. My suggestion though is to add a third view, in addition to the current tiles and list, that does show the full file name. Surely this should be fairly easy as a single column list!

Try writing a book and being unable to the see entire file name for a document. This needs to be done urgently, and it's one reason I do most of my writing in Google drive, which by the way has a nice spellchecker that actually works in Google Docs, One Drive is a clunker for word file storage.
